/** @jsxImportSource preact */
const keyBeforeSpread = <span key="a" {...props} />
const keyAfterSpread =<span {...props} key="das" />Expected behavior:
/** @jsxImportSource preact */
import { jsx } from "preact/jsx-runtime"
import { createElement } from "preact"
const keyBeforeSpread = jsx("span", Object.assign({}, props), "a");
const keyAfterSpread = createElement("span", Object.assign({}, props, { key: "das" }));Actual behavior:
/** @jsxImportSource preact */
const keyBeforeSpread = _jsx("span", Object.assign({}, props), "a");
const keyAfterSpread = React.createElement("span", Object.assign({}, props, { key: "das" }));Playground Link:
